Professional 3D rendering requires a large number of floating point operations (including physical entities, ry conversion, cut, light efficiency, and triangle settings) and integer operations (including triangle settings and pixel rendering ), is a CPU-intensive task. Generally, one way to deal with this heavy task is to use a computer cluster to allocate work to more computers. For example, the famous Digital Domain used the Linux cluster system for the first time in 1997 to handle the special effects of Titanic.

Janne needs to work, and of course it is mainly because of the fun of doing it. She has also set up a micro-cluster system in her home. If you are interested, let's see it.

Because the traditional professional workstation is bulky, expensive, and consumes a lot of power, Janne wants to build a platform at home, with the goal of being small, quiet, power-saving, and low cost. First he bought 6 Core 2 4 Core processor, then look for cheap motherboard, finally selected the gigabyte S Series GA-G33M-DS2R/S2. Each motherboard has a maximum of 8 GB memory, so a total of 48 GB.

One difficulty is to find a suitable chassis, which can put down the six boards and is not too large. Finally, we found that an IKEA Helmer file cabinet is exactly the perfect choice. The staggered Power Supply facilitates the flow of air.

The operating system uses Fedora 8, the open-source distributed rendering management software DrQueue. The six main boards are connected with an 8-port 3com Gigabit Switch, And the other 20-watt Via C7 computer is used as the NFS server.

After a full night of work, the Linux cluster machine has been configured, with a total of 24 cores, clock speed of 2.4 GHz, 48 gb memory, and total power of only 400 watts. The floating point operation capability of this cluster machine reaches 186 Gflops. It takes 9.2 hours to render 24 frames of x4000 pixels in a Mac Pro (dual core Xenon 2.66GHz × 2, 4 GB memory, this file cabinet cluster took 64 minutes.
